Nutritional Flushing of Small Ruminants – Preparing for Fall Breeding

Washington State University Extension, Animal Agriculture
(Previously published on the WSU Extension Animal Agriculture page)

Introduction
Flushing isn’t just an aspect of indoor plumbing—it’s also part of a well-managed flock’s nutrition and reproduction program. This article will address the why’s and how’s of flushing sheep and goats.

Flushing Defined
What is flushing, anyway? The term describes a temporary but purposeful elevation in the plane of nutrition around breeding time. Its objective is to boost ovulation, conception, and embryo implantation rates. Flushing may also increase the proportion of females that exhibit estrus. Boosting these rates increases lambing and kidding rates by Continue reading

Diarrhea is defined as an increased frequency, fluidity, or volume of fecal excretion. The feces may contain blood or mucous and be smelly. The color of the feces may be abnormal. However, it is not possible to definitively determine the infectious organism by looking at the color, consistency, or odor of the feces. A definitive identification requires a sample for microbiological analysis.

In livestock, diarrhea is called scours. There can be many causes of diarrhea: bacterial, viral, parasites, and diet. Continue reading

Forage Analysis: What Numbers Do I Need

Justin W. Waggoner, Kansas State University
(Previously published in The Stock Exchange News: May 30, 2019)

One the more common questions I receive with regard to analytical testing of forages and other feedstuffs is, “I have the sample, now what do I test for or what analysis package should I select?”

The basic components that nutritionists need to evaluate a feedstuff or develop a ration are dry matter or moisture, crude protein, an estimate of the energy content of the feedstuff — Total Digestible Nutrients (TDN), Net Energy for Maintenance (NEm), Net Energy for gain (NEg), and the macro minerals, Calcium and Phosphorous. These are the most basic numbers that are required, but Continue reading

Feeding Long-fed Lambs: The Effect of Energy Source and Level, and Sex on Growth, Performance, and Carcass Characteristics of Lambs

Brady Campbell, Program Coordinator, OSU Sheep Team

If you recall from last week, Jaborek et al. (2017) investigated how feed source and amount of feed offered per feeding affected lamb growth, performance, and carcass characteristics. In that experiment, lambs were fed to live weights of 130 – 140 lbs. and were fed for approximately for 100 days. This system is representative of the Eastern US sheep production. However, this system does not apply to all producers. For those producers that decide to retain lambs for an extended period of time beyond this typical market size and condition, lets try to understand how the number of days on feed affects lamb growth, performance, and carcass characteristics summarizing a paper by Jaborek et al. (2018) that fed lambs for an additional length of time (218 days on feed total). Continue reading

Feeding Lambs: The Effect of Energy Source and Level, and Sex on Growth, Performance, and Carcass Characteristics of Lambs

Brady Campbell, Program Coordinator, OSU Sheep Team

As the month of May comes to an end, there are two thoughts that come to mind. One, early born lambs raised indoors on grain are approaching market appropriate condition (live body weight and fat cover). Two, according to the Ethnic Holiday Calendar provided by the Maryland Small Ruminant program, Eid ul-Fitr (the Festival of Fasting Breaking for the Muslim faith) begins in two weeks. With this being said, shepherds with available lambs may consider selling their lambs in order to capitalize on the increased market value of lamb as a major ethnic holiday approaches just prior to the summer slump. However, marketing lambs towards this type of niche market can be challenging as some holiday dates continuously change from year to year. Although it is too late for this year to change your diets, feeding program, and management practices, it is important to consider what diet your lambs are being fed in order to achieve these marketing goals for the future. Therefore, in order to understand how sex, feed source, and amount of feed offered per feeding affects lamb growth, performance, and carcass characteristics, this week Jaborek et al. (2017) provides us with the data to do just that. Continue reading

The Importance of Water and its Source

Callie Burnett, M.S. Animal and Veterinary Sciences, Clemson University
(Previously published in AGDAILY: March 29, 2019)

The importance of water as a factor in livestock production.

Although it’s “officially” spring according to the calendar, it may be a bit too early for me to extend my congratulations to you for making it through what many of us would call a rough winter. We’re close, but I certainly don’t want to jinx it. Depending on where you’re located, winter is still hanging around and with winter weather comes the not-so-joyous task of “breaking the ice,” literally. If you’re a herdsman or livestock producer, it’s very likely that you’ve had to spend a decent portion of your early mornings breaking ice in buckets, stock tanks, waterers, and the like. Sometimes, despite our greatest efforts, those things just aren’t able to stand up to the (sometimes below) freezing temperatures. Continue reading

Trace Mineral Deficiency

Have you ever wondered whether your stock have a trace mineral deficiency?

Trace minerals such as copper, cobalt, selenium, and iodine are only required in small amounts but are still essential for optimal production, and for life. In contrast, macro-minerals such as calcium and phosphorus are required in larger amounts. Trace mineral deficiencies arise when the amount of the mineral in the food that is available for absorption by the animal through their gut is insufficient to meet their needs.

Growing animals have the highest demand for Continue reading

Scottish Sheep Production Through an American Lens

Brady Campbell, Program Coordinator, OSU Sheep Team

For those of you that followed us on Facebook (OSU Sheep Team) last week, you may have noticed that our postings were a bit different than usual. Over spring break I had the great opportunity to help lead the study abroad trip, Scotland Ruminants. Over the course of our eight day trip, 36 undergraduate Animal Sciences students and 3 advisors toured Scotland’s countryside learning everything from veterinary school opportunities at the University of Glasgow to ruminant production systems in Scotland which included the sheep, goat, beef, dairy, and for our pseudo ruminant friends, alpacas along with much more!

If I were to talk about each part of the trip, you may be reading this for a while. So, with that, I’d like to take a few minutes to compare and contrast Scotland’s sheep industry to ours here in the States. While at the university of Glasgow, Continue reading

The Effects of Dietary Acidity and Sulfur on Feedlot Lamb Performance Fed Dried Distillers Grains with Solubles

Brady Campbell, Program Coordinator, OSU Sheep Team

Last week we featured the article “Benefits to Adding DDGS to Small Ruminant Diets” that outlined several research projects highlighting the benefits of adding dried distillers grains with solubles (DDGS) to sheep and goat diets. As bio-fuel production continues to be a viable industry, understanding how to efficiently and effectively utilize by-products from this industry will be key in livestock feeding profitability.

For those that took the time to view all the links provided in the text, you would have noticed that a couple of those projects were based here at The Ohio State University. Within the US Grains Council report, one summary in particular from Continue reading

Benefits of Adding DDGS to Small Ruminant Diets

Minnesota Bio-fuels Association
(Previously published on the Minnesota Bio-fuels Association webpage: March 1, 2017)

February was National Lamb Month! And we took this annual opportunity to highlight the benefits that DDGS continue to provide within the sheep industry.

A reminder that DDGS or (dried distillers grains with solubles) are a high protein animal feed and one of the co-products made during ethanol production. In Minnesota, every bushel of corn produces about 2.8 gallons of ethanol, 18 lbs. of DDGS and 1.5 lbs. of corn oil. In 2016, Minnesota produced 3.5 million tons of dried distiller’s grains.

The majority of the starch from corn is removed during the process of producing ethanol so the resulting DDGS co-product are a high-energy feed source of concentrated protein and high fiber. According to Iowa State University’s Center for Agricultural and Rural Development, DDGS contain 10 percent to 15 percent more energy than corn grain. Continue reading

Tube Feeding Neonatal Small Ruminants: An Essential Skill for Sheep and Goat Farmers

(Image Source: Dr. Susan Kerr – Washington State University)

Introduction
Lambing and kidding are well under way. It is essential that sheep and goat producers learn how to tube feed young animals. This simple procedure can often save a young animal’s life, thereby increasing lambing and kidding crop rates and enhancing profitability. With a brief amount of instruction and a little practice, even children can perform this crucial task quickly, safely and effectively.

Coccidiosis is a parasitic disease affecting a variety of animals, especially mammals and birds. The causative organism is a microscopic, spore-forming, single-cell protozoa called coccidia. Coccidia are from the same class of organisms (sporozoa) that cause malaria. Coccidia are sub-classified into many genera. In sheep and goats, coccidiosis is caused by the genus Eimeria [6].

Within this genus, there are more than Continue reading

Fact Sheet: Late Gestation/Early Lactation Ewe Nutrition

Dr. Reid Redden, Extension Sheep and Goat Specialist, Texas A&M AgriLife Extension Service
Reviewed by: Dr. Dan Morrical, Sheep Extension Specialist, Iowa State University
(Previously published online as a Let’s Grow Fact Sheet)

Although it may be a bit late this year to change your ewe feeding and management programs, I still find it important to share as you observe your flock this year. Are your ewes in a good body condition score? If not, what could you have done differently to improve? Supported by the Let’s Grow program through the American Sheep Industry, Dr’s Reid Redden and Dan Morrical provide us with some helpful tips to keep our ewes in good shape to prepare for late gestation and early lactation.

Improper nutrition during the last month of gestation and early lactation can have devastating effects on lamb survival and productivity. Most of which occur when ewes are in a poor body-condition score (BCS) entering the last trimester of pregnancy. Therefore, ewe-feeding strategies to maintain productivity and survival of lambs starts well before this critical time period.

Practical Aspects of Improving Lamb Survival

Matthew Ipsen, Nuffield Scholar
(Previously published online on Making More from Sheep)

The reproductive performance of ewes is certainly an economically important trait in any commercial enterprise. Attention should be paid to the care of pregnant ewes and their lambs before, during and after birth.

Ensuring the nutritional demands of ewes during each stage of pregnancy, will result in the greatest “return on investment” in terms of maximizing the reproductive performance of sheep and in improving lamb survival.

Effects of Dietary Fat in Lamb Feeding Diets

Brady Campbell, Program Coordinator, OSU Sheep Team

If you recall from an article published earlier this month, Dr. Relling and his lab investigated the effects of supplementing fat to gestating ewes. Dr. Relling’s lab compared the supplementation of saturated and monounsaturated fatty acids (MUFA’s – calcium salts of palm oil) to polyunsaturated fatty acids (PUFA’s – eicosapentaenoic and docosahexaenoic acids) on the performance of lambs who’s dam were fed these fatty acids. Through their experiments, Dr. Relling’s lab demonstrated that lambs reared from ewes supplemented with PUFA’s had greater weight gains and therefore a greater economical value when compared to lambs reared from ewes supplemented with MUFA’s.

In taking these points into consideration, producers may Continue reading

Cold Water, Cold Livestock

Although Ohio and Wyoming weather conditions may differ, this weekends cold spell put shepherds to the test as lambs continued to hit the ground. Ensuring that our small ruminants have an ample supply of fresh water is on every producers check list, but monitoring water temperature may not be. Water temperature may play a bigger role than you thought before. To learn more, be sure to read on below!

One of the outcomes of having a high lambing/kidding percentage (greater than 200%) is that you may end up with some lambs/kids that you have to raise artificially. While some ewes/does will be able to raise triplets (even quads), sometimes it may be necessary (or wise) to remove lambs/kids from large litters in order to obtain more satisfactory weight gains.

There are different opinions as to which offspring should be removed for artificial rearing. Traditionally, it was recommended that Continue reading

Can Restricting Feed Intake Benefit your Lamb Feeding Program?

Brady Campbell, Program Coordinator, OSU Sheep Team

With lambing season upon us, many are concentrated on getting lambs on the ground and getting them off to a good start. Although this is an extremely important step in the continual management of your flock, we must also be thinking one-step ahead. By this I mean, what will be your feeding strategy after your lambs are weaned a few months from now. Some producers may decide to sell their lambs as feeders directly after weaning, but for those that decide to retain their lambs and feed them out, how will your lambs be fed? What will your diet be composed of and will you be providing the diet at ad-libitum or at a restricted intake? Thinking about this, have you ever considered how the feeding strategy you choose could affect the feed efficiency and performance of your growing lambs? If you haven’t, no worries. Thankfully, Murphy and others (1994) did just this to Continue reading

Feeding Fat to Pregnant Ewes

Dr. Ale Relling, Assistant Professor, Department of Animal Sciences, The Ohio State University

Should we feed fats to pregnant ewes?

This question is being posed in order to summarize what was presented on December 1, 2018 at the Buckeye Shepherd’s Symposium on feeding fats to pregnant ewes. Before I enter into the details of the results and economic implications, I would like to clarify two things. First, we must consider ruminant physiology and applicability, noting that the sources of fats/lipids used are commercially available products. Second, the goal of all studies were not to improve or change ewe physiology, but to evaluate the effect of feeding fats during gestation and the impact that they had on the offspring.

Winter Feeding of Sheep and Goats: General Rules of Thumb for Gestating and Lactating Females

Knowing the nutritional requirements of females during the various stages of production allows producers to ensure females are performing at optimal levels. Since females are typically in late gestation and/or lactating during the winter months, when their nutritional needs are the highest, it is even more important to ensure the females are obtaining the proper roughages and/or grains in their diets. Below are Continue reading

Keeping Newborn Lambs Fed and Warm

Jeff Held, South Dakota State University Sheep Extension Specialist
(Previously published on iGrow, a service of SDSU Extension)

Newborn Lamb Care Management.

Proper newborn lamb care is a critical component of flock profitability. In the U.S., lamb mortality from all causes is approximately 20% with more than 80% of those losses occurring in the first two-weeks following lambing. Yet a solid lamb care management plan coupled with a few key tools in the lambing barn can sharply improve the number of lambs reared per-ewe. Generally, the top causes for newborn lamb losses are starvation, hypothermia (cold stress), respiratory disease, and scours followed by injury. Theoretically, these categories each stand alone, however the reality is often two-or-three of these occur simultaneously. Producers that develop a lambing time-management plan to incorporate appropriate lambing tools and gain key skills on newborn lamb care will benefit from less labor input and expense with a greater number of lambs weaned.

Colostrum is the key to raising healthy goat kids and lambs.

Ensuring goat kids and lambs get enough colostrum at birth is imperative to getting them off to a good start.

One of the most important functions of colostrum (first milk) is to provide kids and lambs with antibodies (immunoglobulins) that provide passive immunity for the first two months of life. Newborn lambs and kids, like other mammals, are born with no antibodies of their own and rely on those provided by the mother in colostrum for protection.

Protection provided by Continue reading

Creep Feeding Primer

Creep feeding is a means of providing supplemental nutrition to nursing lambs and kids. It is accomplished by giving lambs and kids access to extra feed or better pasture, while excluding their dams.

Lambs and kids that are born in the winter months are often creep fed, since pasture is usually not readily available. Show animals are typically creep fed, in order to get them bigger for show.

Creep feeding is recommended for accelerated lambing and kidding programs, in flocks and herds where there are a lot of multiple births, and anytime milk production is a limiting factor. Artificially-reared lambs and kids should be creep fed to facilitate early weaning. Creep feeding is also advisable when Continue reading

Listeriosis Control and Prevention

Michael Metzger, Michigan State University Extension Educator
(Previously published on MSU Extension, Sheep & Goat: November 28,2018)

Listeriosis is a disease that can affect all ruminants, as well as other animal species and humans.

Listeriosis is an important infectious disease of sheep and goats. It most commonly causes encephalitis but is also capable of causing blood infections and abortion.

Listeriosis is caused by the bacterium Listeria monocytogenes and is commonly seen in cooler climates. These bacteria can be found in the soil, food sources and even the feces of healthy animals. Most commonly, this disease of sheep and goats is observed as a result of feeding moldy or spoiled hay or silage. It’s possible for sheep and goats to become infected without feeding moldy or spoiled hay or silage, as it is also found in the environment. The bacteria are very hardy and are common in soil.

Possible locations of Listeria monocytogenes bacteria: Continue reading

Pregnancy Ketosis

New producers of small ruminants often learn about pregnancy ketosis first time the hard way—with a dead dam, fetuses or both. This article explains the causes of pregnancy ketosis (a.k.a. toxemia) and more importantly—how to prevent it.

This ewe had milk fever, but advanced pregnancy ketosis would present similarly: a down and depressed animal with poor appetite. Lack of complete recovery after calcium treatment and results of ketone tests would help differentiate these two conditions. Also, milk fever usually occurs after lambing and pregnancy ketosis before. Photo courtesy Susan Schoenian, University of Maryland Extension.

Sheep and goat fetuses add 70% of their final birth weight in the last six to eight weeks of gestation. A singleton increases a dam’s nutritional requirements by 1.5 to 2 times maintenance in the last trimester. Multiple fetuses greatly increase energy demands on their mother: twins require 1.75 to 2.5 times maintenance requirements and triplets demand up to 3 times maintenance. Twins and triplets are common in some breeds of sheep and goats; quadruplets and even more are not uncommon in Boer goats, Finnsheep and Romanov sheep. Continue reading

Hay Buying Help and Preparation for Next Year

Garth Ruff, OSU Extension Educator ANR, Henry County

With last week’s rain showers leaving much of the area saturated, there were limited opportunities for farming or even yardwork. I took advantage of the soggy conditions here in NW Ohio and headed south on Friday to a fairly productive couple of days in Morgan County. We had a good chance to winterize and store all of the hay equipment and tractors that we typically don’t use during winter time.

Regarding hay implement storage, we make an effort blow off the chaff, seeds, and dust with a leaf blower shortly after use and then pressure wash the piece prior to pulling in to the machinery shed for the down season. Once everything is cleaned off, each machine is greased and gear boxes are checked for fluid levels. Any major repairs or maintenance such as Continue reading

Grazing Damaged Corn and Corn Residue

Dr. Jeff McCutcheon, OSU Extension Educator, Southeast Regional Director

Pulling this article from our achieves this week, it seems to be extremely timely and beneficial as mother nature has made it challenging to harvest crops this fall in a timely manner. As we progress later into the harvest season, stalk quality will decrease which could lead to more down corn in our fields. From a cropping standpoint, this is an issue as some of the downed crop may not be salvageable. Luckily not all is lost if we are able to incorporate a strategic grazing plan.

To survive the current feed economy livestock producers need to graze their livestock as long as they can.  Every day livestock are meeting their nutritional needs through grazing they are being fed as economically as possible.  Typically cattle producers utilize corn and corn residue as a feed source but, in Ohio, sheep producers need to consider grazing Continue reading

Ewe Management Tips: Mid and Late Gestation

Some important topics to consider with the beginning of lambing season just around the corner.

Proper management and nutrition of the ewe flock during mid and early lactation are critical for optimizing flock productivity and profitability. Balanced nutrition, coupled with proper management during gestation is important for fetal development, lamb vigor and survival at birth. Additionally, proper nutrition during gestation is important to prevent nutritional disorders which may impact the health and performance of the ewe and her lambs, and influences milk production of the ewe.

There are several factors that affect the nutritional needs of the ewe during gestation, with primary considerations for: Continue reading

Livestock Winter Hay Needs

Dr. Susan Kerr, Washington State University, Northwest Regional Livestock and Dairy Extension Specialist
(Previously published on the Oregon State University Small Farms Page)

Livestock producers can often realize feed cost savings by purchasing their entire winter hay supply at one time. Obtaining an entire feeding season supply from a new hay crop certainly beats underestimating needs and having to cobble together purchases of more hay in late winter, when demand may outstrip supply and quality may be variable. There are four critical aspects of large hay purchases: knowledge of how much to purchase, adequate storage capacity, ability to work with the hay producer’s schedule and capital to make the purchase.

A few simple calculations can help livestock producers estimate how much hay they will need to get them through the winter. Estimates are based on Continue reading

Ewe Winter Feeding Systems, the Long Term Effects on Lamb Performance

Brady Campbell, Program Coordinator, OSU Sheep Team

As we approach the winter months, I find it timely to discuss what types of feedstuffs are available to feed gestating ewes. Last fall I published a summary from Radunz and others (2011) that covered the effects of winter feeding systems on ewe performance which can be found by clicking this link. For those not able to access the link, three different diets were fed to gestating ewes during the last 90 days of gestation which consisted of either forage (haylage), grain (limit fed corn), or by-products (limit fed dried distillers grains). After birth, all ewes were fed the same lactation diet.

From an economic perspective, feeding by-products proved to be roughly $0.01/head/day cheaper than Continue reading

Stiff lamb disease – nutritional muscular dystrophy.

What is it?
White muscle disease (WMD) is a degenerative muscle disease found in all large animals. WMD is caused by a deficiency of selenium and/or vitamin E. Generally, it is not known which. Selenium (Se) deficiency is associated with selenium deficient soils and the inadequate uptake of selenium by forages grown on these soils. Certain areas of the U.S., including the Northeast, are considered low in selenium levels. Selenium deficiency occurs when the soil contains less than 0.5 mg Se/kg of soil and locally harvested feeds contain less than 0.1 mg Se/kg of feed. Continue reading

Feeding Strategies to Increase Lamb Performance, Carcass Characteristics, and Consumer Acceptability

Brady Campbell, Program Coordinator, OSU Sheep Team

For most producers, maintaining high standards
of animal welfare and increasing production efficiencies rank among the most important factors involved in livestock production. While focusing on production efficiencies, what can producers do in order to help make their livestock more efficient? We know that excess fat on the carcass of an animal is considered inefficient as excess fat will be trimmed off, disposed of during the fabrication process, and does not contribute to final lean yield. In the case of lamb, excess fat can be a challenge as fat is associated with flavor and in turn the overall acceptability of the product. In order to produce a product that is acceptable for consumers from both a flavor and palatability standpoint, producers have access to different management strategies that can be implemented in order to change the performance and carcass characteristics of fed lambs. In order to determine Continue reading

Chronic Copper Poisoning in Sheep

Dr. S. John Martin, Veterinary Scientist, Sheep, Goat, and Swine
(Previously published on the Ontario Ministry of Agriculture, Food, and Rural Affairs web page)

How does chronic copper poisoning (CCP) occur?
Sheep are the domestic animal most prone to CCP. They absorb copper from the diet in proportion to the amount of copper offered, not to the body’s need as with the absorption of other minerals. Any excess absorbed copper is stored in the cells of the liver, eventually reaching toxic levels. Levels in the liver above 500 ppm dry weight are usually considered toxic. This storage in the liver can take months or even years to reach a toxic level. The elimination of copper from the body through the kidneys is slow.

Even then, it needs a stress to release the copper. This stress can be weather, poor nutrition, transportation or handling. The liver cells rupture, releasing copper into the blood stream. There are suggestions that excess liver copper can Continue reading

Breeding ewe lambs and doelings.

Should ewe lambs and doelings be bred to produce their first offspring when they are approximately one year of age? Or should you wait until they are yearlings to breed them for the first time? The answer depends. There are many factors to consider and there are pros and cons to each breeding decision.

Breeding ewe lambs and doe kids allows you to exploit their reproductive and genetic potential. It is well-documented that ewes that are mated as lambs will have a higher lifetime production than ewes that are mated for the first time as yearlings.

One of the most compelling reasons to consider breeding ewe lambs and doe kids is Continue reading

Adding Distillers Grain and Soy Hulls to Sheep Diets

Jeff Held, SDSU Sheep Extension Specialists
(Previously published as an Extension Extra: South Dakota State University Cooperative Extension Service)

Feeding Soy Hulls and Dried Distillers Grain with Solubles to Sheep

Co-products from corn and soybean processing industries can be excellent sources of nutrients for livestock. With the growth of ethanol production from corn and increasing number of soybeans processed in the Upper Midwest, livestock producers have many nutrient-dense co-product feed resources readily available. In the Upper Midwest distillers dried grain with solubles (DDGS) derived from ethanol production and soybean hulls (SH) from soybean processing have created the greatest interest to sheep producers.

Interestingly these co-products are both high fiber-low starch in content, much like forages. Yet DDGS is classified as a protein feed and SH could be classified as an energy feedstuff.

As often found with co-product feed ingredients, these have unique nutrient profiles and physical characteristics that require attention when formulating diets. They often can serve multiple roles in diet formulation: Continue reading

Using Hay to Meet Sheep Nutritional Needs

Rory Lewandowski, OSU Extension Educator ANR, Wayne County
(Previously published in: A Guide to Katahdin Hair Sheep)

Sheep are ruminants, so outside of a feedlot situation the majority, if not all, of their nutrient requirements should be met from forages. For most sheep owners, this means that hay is an important component of the ration through at least the winter months and possibly even longer, including times of pasture shortages due to drought or poor forage stands. There are two critical questions to answer when using hay to meet sheep nutritional needs:

  • What is the nutrient content and quality of the hay?
  • What are the nutrient requirements of the sheep?

The number one factor affecting the quality and nutrient content of hay is Continue reading

Identifying Corn Ear Rots (Image Source: No-Till Farmer)

Introduction
During the 2009 Indiana corn harvest, livestock producers heard numerous reports of mycotoxin levels high enough to cause concern. The main mycotoxins in feed grains that sheep and meat goat producers need to be concerned with are deoxynivalenol (DON) and zearalenone (ZEN). Deoxynivalenol is also known as vomitoxin. Zearalenone arises from Gibberrella ear rot, or Gib ear rot. Both of these mycotoxins are produced by a Fusarium fungus. There is a limited amount of research and extension information available on the effect of sheep performance when consuming feeds infected with DON and ZEN.

Mike Rankin, Hay and Forage Grower managing editor
(Previously published in Hay & Forage Grower: June 26, 2018)

One of the many things that David Letterman gets remembered for is his Top 10 lists.

These lists included such things as the Top 10 Signs Your Kid Had a Bad First Day at School, the Top 10 Numbers Between One and 10, and the Top 10 Dog Excuses for Losing the Dog Show (No. 3 – Didn’t know that was the judge’s leg).

Lists, especially those that are ranked, are great for generating a plethora of discussion and arguments — just ask two passionate baseball fans to list the top 10 players during the past 50 years. It’s likely both will end their day in an emergency room.

Agree or not, lists do invoke thought and reflection.

With that in mind, here’s Dennis Hancock’s “Top 7 Factors that Affect Hay Forage Quality.” The University of Georgia Extension forage specialist enumerated the list during a recent Alabama Forage Focus webinar. The factors are listed in order of perceived importance. Continue reading

Why Ewe Should Control Feed Intake
** Follow the link above to view the Ag-note.

This weeks Ag-note comes from OSU students Carolina Fernandez, Dermot Hutchinson, Randi Shaw, Jake Parkinson, and Caitlyn McCaulley as they present a detailed overview on the importance of controlled feed intake in small ruminants. The students were inspired by Dr. Francis Fluharty to present on this topic as Dr. Fluharty expressed that this type of feeding strategy is not just limited to feedlot cattle. Although controlling feed intake comes with a cost due to an increase in labor and time spent feeding, the benefits from this strategy certainly outweigh these costs.

At a basic level, producers have two options when it comes to feeding strategies, Continue reading

Energy Intake and Protein Concentration Effects Lamb Performance and Visceral Organ Mass

Brady Campbell, Program Coordinator, OSU Sheep Team

As summer approaches, I can’t help but to think about the upcoming breeding sheep show season, when will Mother Nature let us to make our first cutting of hay in southeastern Ohio, and the number of lambs that are on feed in the state of Ohio. For those producers that are feeding out lambs, I have a few management questions to ask. Currently, how are you feeding your lambs? Are your lamb’s offered ad libitum access to feed all day or are you feeding your group of lambs at a specific rate (i.e. percent of body weight)? When formulating your rations, how are you determining the percent protein needed in your lamb diets? Are you feeding Continue reading

The Effects of Finishing Diet and Weight on Lamb Performance, Carcass Characteristics, and Flavor

Brady Campbell, Program Coordinator, OSU Sheep Team

The beauty of the small ruminant industry is that producers are able to capitalize on niche markets that surround religious holidays. Unfortunately, it is clear that the price of lambs at the sale barn has dropped as seen in recent market reports, with the conclusion of Christian and Orthodox Easter’s as well as Passover. Checking the calendar, it appears that we are approaching both Ramadan (month of fasting beginning May 6) and Eid al-Fitr (June 5-7). The occurrence of these religious holidays may allow for the lamb market to see an increase in market prices, but many fall and winter born lambs in the eastern US will also be entering the market as they approach finishing weights and in turn may flood the market. Therefore, as a producer, it is important to have a marketing plan in mind when making breeding decisions for proper lambing dates.

Aside from religious holidays, lamb Continue reading

With Sheep, The Cheapest Mineral Isn’t

Dr. Francis Fluharty, Research Professor, Department of Animal Sciences, The Ohio State University

Regardless of the animals stage of production or time of year, Dr. Fluharty reminds us that mineral supplementation is important! Although mineral

(Image Source: Back Yard Herds)

can be quite costly initially, Dr. Fluharty outlines the risks and production losses associated with the lack of mineral supplementation.

The major nutritional requirements are: water, energy, protein, minerals, and vitamins. In many cases, sheep producers do a good job of providing adequate water, energy, and protein. However, many sheep producers buy ‘cheap’ minerals, ignoring the fact that the availability of the minerals in the oxide form is low. In many of these mixes, only 10-20% are Continue reading

How Often Should You Cut Alfalfa?

Dr. Mark Sulc, OSU Extension Forage Specialist, The Ohio State University

Most dairy producers are fairly aggressive with alfalfa cutting schedules. Their goal is to achieve high-quality forage.

But cutting too frequently usually shortens the life of alfalfa and often gives lower yields, even when more cuttings are taken per growing season.

Recent results from a two-year study at the Western Agricultural Research Center of The Ohio State University demonstrate the yield and quality trade-off. Continue reading

Management Practices that can Affect the Flavor Intensity of Lamb

Jerad Jaborek, Graduate Research Associate, The Ohio State University

Now is the time of year when the majority of winter lambs are being weaned. After weaning, these lambs will be sold at the sale barn

or retained on the farm to be placed on feed to reach market ready weights. Have you ever considered that the way we manage these lambs will affect the flavor intensity of the sheep meat produced from these lambs?

According to 2015 National Lamb Quality Audit, which conducted surveys with people working in the lamb supply chain (retailers, food service, and purveyors) to rank the importance of quality attributes. Eating satisfaction was the most important attribute to survey participants and was commonly defined as the Continue reading

Pasture: Evaluation and Management of Existing Pasture

Bob Hendershot, Retired State Grassland Conservationist

As we begin to move into spring, we need to start thinking about spring forage growth and how we will be managing our pastures over the course of the new year.

Pasture management is very important for grazing animals; cattle, horse, llama, and sheep owners. By managing pastures more effectively, land managers can increase forage production, lower production costs, improve aesthetics, and promote a healthier environment. The benefits of a well-managed pasture include reducing environmental impacts of your operation, including movement of soil and manure to water bodies; improving property aesthetics, which makes for good neighbor relations, and increases property value; and providing feed and recreation for your horses. Using a rotational grazing system can enhance these benefits.

For optimal health, horses and llamas need to eat 1 to 1.5% and cattle and sheep Continue reading

Hypothermic Lambs: How to Defrost before They’re in the Freezer

Jackie Lee and Kathrine Yunker, 2019 College of Veterinary Medicine DVM Candidates, The Ohio State University
(previously published on Talking Sheep – Sheep Education and Information: February 19, 2018)

Although mother nature can not make up her mind when it comes to the weather, this piece of information still serves a great purpose as it reminds us about the issues that can arise as a result of hypothermia and hypoglycemia as well as the management practices that can be implemented in order to decrease the losses associated with both of these issues.

Winter has already been harsh this year, making it only fitting to write about hypothermia in lambs. Even with the best management, this is bound to be an issue for many sheep producers. Hypothermia has many causes and can affect lambs at different ages. In newborn lambs less than five hours old, hypothermia often occurs due to prolonged exposure to cold temperatures.

Difficult or premature births can Continue reading

Livestock Water is Essential, Even in Winter

Ted Wiseman, OSU Extension Educator ANR, Perry County

Water is essential for all livestock regardless of the time of year. So far this year we have certainly had our share of chopping ice, thawing water lines and troughs. With recent temperatures many of us often focus on keeping livestock well fed and with adequate shelter. However, often times we forget about the most important nutrient which is water. Water consumed by livestock is required for a variety of physiological functions. Some of these include proper digestion, nutrient transportation, enzymatic and chemical reactions, and regulation of body temperature.

Although water is the cheapest nutrient we may purchase or provide, it is the one we provide the most of on a per pound basis. For example, every pound of dry matter consumed, Continue reading

Graze on Cool-Season Annuals – Thoughts for your 2018 Grazing Year

Curt Arens, Farm Progress field editor
(previously published in Nebraska Farmer: February 7, 2018)

Oats, barley, triticale, and spring wheat all make for good grazing and hay crops when they are spring-seeded.

For a seed cost of between $25 and $31 per acre, livestock producers can gain valuable grazing days or hay by planting cool-season annuals in the spring or fall. All kinds of annuals can be planted in the spring, according to Nebraska Extension educator emeritus, Dennis Bauer.

Speaking at a Beef Profit Tips meeting in Center, Neb., recently, Bauer said oats, spring triticale, spring beardless barley, Italian or annual ryegrass, field peas, and other legumes all make good grazing or hay options.

Management Considerations to Lower Lamb Mortalities

Dr. Bill Shulaw, OSU Extension Veterinarian

Once again, we have dug back into the achieves to provide an article by Dr. Bill Shulaw that outlines management strategies that can be implemented in order to decrease lamb losses associated with improper management and disease control that may be prevalent during the first few weeks of life. Whether you have raised sheep for a year or 50 years, reviewing this article would benefit all shepherds as it outlines simple control and management strategies that can certainly benefit any operation.

There are many factors that affect lamb survival. Serious shepherds should consult the Sheep Production Handbook, produced by the American Sheep Industry Association (www.sheepusa.org), for a more complete discussion of the various conditions and infectious diseases which impact lamb survival. However, Continue reading

Do Sheep and Goats get Cold?

Erika Lyon, OSU Extension Educator ANR, Jefferson and Harrison Counties

During this time of year, the hills of eastern Ohio are covered in snow, frozen waterfalls, and massive icicles. Most of us enjoy spending these cold winter days indoors next to the fireplace or with the furnace working overtime. So with their thick wool coats, are sheep actually keeping as warm as you think? What about goats that do not have those nice thick coats? Are they just used to the cold? During the winter, extreme temperatures, precipitation and wind can create Continue reading

How can Delayed Weaning Benefit your Operation?

Brady Campbell, Program Coordinator, OSU Sheep Team

At what age do you wean your lambs? This is a question that I have asked producers many times. I have heard ages ranging from 35-130 days of age with the most common answer being 60 days of age. This is the most common weaning age for producers in the eastern United States. When I ask producers why they wean their lambs at 60 days of age or younger, most respond with “that’s the way we have always done it here on the farm, so why change now?”

From a researcher’s perspective, this is not a valid answer. Weaning before the natural weaning age (between 100-180 days of age depending upon sheep breed) is stressful. Weaning stress can lead to decreases in animal performance as demonstrated by decreased weight gain. Weaning stress can also result in decreased animal health as shown by decreases in immune system function that can lead to an increased susceptibility to disease and infection. However, if we were Continue reading

What Accounts for Variability in Grain Protein Levels in Corn?

(previously published in the C.O.R.N. Newsletter 2018-01)

(Image Source: C.O.R.N. Newsletter)

We’ve recently heard comments and questions concerning the varying levels of grain protein levels being found in shelled corn. Some feed companies have reported seeing many samples in the upper 6% and lower 7% protein range this year but there are reports of levels that are nearly 9%. Some feed mill operations are using 7% as the default value based on this year and last year’s levels. However, in the past, higher grain protein levels (% +2) have been cited for corn. Are the reports of low levels in 2016 and 2017 an anomaly? What could be accounting for these varying protein levels in corn?

Environmental conditions (esp. those affecting soil moisture), cultural practices (nitrogen fertilization, plant population, drainage) and hybrids genetics all influence grain protein. Production factors and favorable growing conditions that Continue reading

Hay Testing for Efficient Winter Feeding

Christine Gelley, OSU Extension Educator, Noble County

As the new year begins, most Ohio graziers are probably feeding a good portion of hay as a part of their animals’ daily ration. Even if there is a supply of stockpiled forage available, we tend to make hay available just in case they need a little extra. It is likely that grain is also part of that daily ration. Well, how do you know how much hay, grain, and pasture they need? No one wants to leave their animals hungry. In addition, we do not want to waste time or money with unnecessary feeding. Figuring out the balance can seem like a guessing game, but the place to start is with a hay test.

Testing the hay you are feeding is well worth the price of sample analysis. Collecting a sample is not complicated and typically, results are available Continue reading

How do Finishing Diet Combinations Affect Lamb Performance and Tissue Growth?

Brady Campbell, Program Coordinator, OSU Sheep Team

For those shepherds in the state of Ohio that retain their lambs and finish to a market weight, a high concentrate finishing diet is commonly used. High concentrate diets are favored by producers as these types of diets allow producers to raise their lambs indoors away from predators, at a low cost when grain prices are low, and allow their lambs to reach a market ready weight at an earlier time point when compared to forage fed lambs. However, in today’s market, the production of grass-fed meat products receives a premium. Therefore, in order to capitalize on these premiums, some producers may choose to produce grass fed or pasture raised lamb.

When switching to alternative backgrounding and finishing diets, it is important to understand Continue reading

We’re Pricing Hay all Wrong

Mike Rankin, Hay and Forage Grower managing editor
(Previously featured in Hay & Forage Grower: December 12, 2017)

(Image Source: Mike Rankin, Hay and Forage Grower)

“We need to think about alfalfa as a package of nutrients,” said Bill Weiss, Ohio State University Extension dairy nutritionist. “As such, the value of that alfalfa (or any forage) should reflect the value of the nutrients provided.”

Perhaps most buyers and sellers of hay already think this is being done, but Weiss takes it to another level. He shared his thoughts on valuing hay at the Western Alfalfa & Forage Symposium’s Hay Quality Workshop held in Reno, Nev. Continue reading

New Study: Don’t Graze Fescue to the Ground

Lauren Peterson, Hay and Forage Grower summer editorial intern
(Previously featured in Hay & Forage Grower: December 5, 2017)

The verdict is in. Grazing toxic fescue to the ground is dangerous to pastured livestock. Findings released by the University of Missouri indicate that the highest levels of toxic alkaloids are held in the bottom 2 inches of infected grass.

Sarah Kenyon, an MU extension agronomist based in West Plains, Mo., documented these findings in her Ph.D. dissertation.

Kentucky 31 fescue, the most-used grass in Continue reading

Grazing Wind Damaged Corn Residue

Dr. Jeff McCutcheon, OSU Extension Educator, Southeast Regional Director

Although this information has been posted in the past, as harvest has come and gone, this opportunity may serve as a viable option for those looking for a cheap feed source to graze the mature ewe flock on. This strategy allows farmers to optimize on losses associated with harvest as well as serve as a means to save on winter feedings.

To survive the current feed economy livestock producers need to graze their livestock as long as they can.  Every day livestock are meeting their nutritional needs through grazing they are being fed as economically as possible.  Typically cattle producers utilize corn residue as a feed source but, in Ohio, sheep producers need to consider grazing Continue reading

What Finishing Diet Should I Feed my Lambs?

Brady Campbell, Program Coordinator, OSU Sheep Team

Do lambs perform and hang better carcasses when grazed on grasses, legumes, or fed an all concentrate diet?

Before to asking these questions, producers must first determine the goal of their operation. Resources such as land, labor, time, and money all play a critical role in the daily management of an operation. In today’s society, there are two types of consumers. Those that want access to quality protein sources at low prices, and those that are willing to pay a premium for specialty products (i.e. grass-fed lamb). When grain prices are low, it may be more economical for producers to finish lambs on grain. However, in order to reach a premium through specialty markets, producers may choose to finish their lambs on pasture. Regardless of which finishing strategy is chosen, producers need to understand both Continue reading

Don’t Guess, Forage Test!

Al Gahler, OSU Extension Educator, Sandusky County
(originally published in the Ohio Cattleman, late fall 2017 issue)

Regardless of livestock species, it is important to test your forages. When in doubt, test them out!

Across most of Ohio, 2017 has been a challenging crop year, especially for those in the hay production business. In 2016, while most producers did not have significant yields, quality was tremendous due to the dry weather which allowed for highly manageable cutting intervals and easy dry down. Since the end of June, however, 2017 has been just the opposite, with mother nature forcing many bales to be made at higher than optimal moisture levels, and cutting intervals measured in months rather than days.

With adequate moisture throughout most of the state for much of the summer, this equates to substantial yields, which in turn for the beef producer, means hay is readily available at reasonable prices. However, for the astute cattleman that either makes his/her own hay or knows the nature of the business, this also means high quality hay may just be the proverbial needle in the haystack, and for the most part, as the old adage goes, you get what you pay for.

While there are many options to manage the situation, including Continue reading

Winter Feeding Systems, Which is the Best for You?

Brady Campbell, Program Coordinator, OSU Sheep Team

The effects of winter feeding systems in gestating sheep on ewe and lamb pre-weaning performance.

As the breeding season comes to an end and winter approaches, it is important to consider how pregnant ewes will be managed as lambing season approaches.

There are several options available to producers for winter feeding strategies such as stockpiling forages on pasture, stored hay, grains, and recently the use of byproducts. Winter feeding can be a challenge as providing enough energy to meet the maintenance requirement of the gestating ewe and growth of the fetus becomes difficult.

Fall and Winter Grazing Strategies

Dr. Jeff McCutcheon, OSU Extension Educator, Southeast Regional Director

In Ohio it is possible to graze year round. Of course grazing in winter does take planning. Summer is the best time to plan for fall and winter grazing. Why? Because many of our options have tasks associated with them in summer. By planning ahead it is possible in Ohio to have adequate quality, grazable forage for most of the winter. Depending on the class of livestock and their stage of production it is possible to need to feed for weeks in winter as opposed to months.

The cheapest option for fall grazing is Continue reading

How Does Harvest Weight and Diet Affect Carcass Characteristics?

Brady Campbell, Program Coordinator, OSU Sheep Team

The most common method for finishing lambs in the United States is the use of a high concentrate diet. Although high concentrate diets allow for lambs to be finished at a younger age, one down fall of this feeding strategy is that lambs may to accumulate an excessive amount of carcass fat. An alternative method to finish lambs would be the use of pasture. Forage fed lambs develop less carcass fat, but require a longer period of time to finish and are harvested at an older age when compared to concentrate fed lambs. In order to determine which feeding strategy will yield the greatest amount of marketable product, a comparison of light and heavy weight lambs on two different diets has been summarized.

In order to make this comparison, lambs were harvested Continue reading

What Benefits are Gained by Processing Grain Fed to Sheep?

Brady Campbell, Program Coordinator, OSU Sheep Team

How does corn processing and fiber source affect feedlot lamb performance, diet digestibility, nitrogen metabolism?

(Image source: Maine Organic Farmers and Gardeners Association)

Behaviorally, sheep and cattle are very different, especially in the way they eat. Sheep are more selective in their eating pattern and spend more time physically chewing and breaking down their feed than cattle do.

Regardless of the animal we are feeding, it is common practice in the livestock feed industry to process the grains fed to our animals. An issue with feeding processed grain is that due to an increase in surface area, the starches in grain become more readily available for the animal to digest. As a result, an increase in digestion may lead to metabolic issues such as acidosis in our ruminant species.

Therefore, a question of interest that arises is can sheep be fed unprocessed grains without Continue reading

The Future of Finishing Lambs

Brady Campbell, Program Coordinator, OSU Sheep Team

Can the implementation of growth promotants or forage grazed finishing diets increase lean muscle gain in lambs without increasing carcass fat?

Marketing lambs at a high lean to fat carcass ratio is important in producing consistent and quality retail lamb products.

Lambs fed high concentrate diets finish at a younger age when compared to forage fed lambs. However, lambs fed high concentrate diets accumulate more carcass fat than lambs on grazed forage diets. The use of either growth promotants or forage finishing diets may provide producers with Continue reading

Fall Grazing Management and Plant Health

Rory Lewandowski, OSU Extension Educator, Athens County

The experienced grazier knows that how grass pastures are managed in the fall of the year determines what they have to manage in the spring of the year. While we tend to think of fall as bringing an end to pasture growth, it turns out that this is a critical time for the grass plant.

In fact, for our perennial grass plants, fall is not so much an end as it is a beginning, or at least laying a foundation for a beginning. Although seed production is one way Continue reading

More Tips for a Successful Fall Grazing Plan

Dr. Jeff McCutcheon, OSU Extension Educator, Knox County

Fall is an excellent time to complete several pasture related tasks. There are activities a livestock producer should be doing to help the pastures survive winter and remain productive next year.

The first and most important activity is good grazing management. Specifically, keep animals from overgrazing. Overgrazing in the fall could ruin next years forage production. It is more critical now than any other time of the year. Overgrazing is not caused by having too many animals in a field. It occurs Continue reading

Sudangrass, Could it Work for You?

Rory Lewandowski, OSU Extension Educator, Athens County

Raising sheep within a pasture based production system presents the manager with two challenges; internal parasite control and summer slump production of cool season pastures.  The use of a warm season annual like sudangrass may offer the pasture based sheep producer a parasite control option while at the same time filling in the forage production slump demonstrated by cool season pastures during the hot summer months.  In this article, I’ll draw on some of the results and lessons learned using sudangrass during the summer of 2007 on the Curt Cline farm in Athens County.
